WILLIAM F. JULIAN, OF MEDORA, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 313,871, dated March17, 1885.

(No model.)

To all whom, it may concernw Be it known that I WILLIAM F. JULIAN, acitizen of the United States, residing at lWIedora, in the county ofJackson and State of Indiana, have invented certain new and usefulImprovements in Oar-Couplings; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and totheletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to devices for coupling and uncouplingrailway-cars; and its object is to avoid the necessity for the operatorto go between the cars. In the center and length of a draw-bar I place adisk-wheel held upright by grooves attached to the floor and ceiling andinclined to the mouthof the drawbar, so that whenever the coupling-pinis lifted the wheel rolls under it by force of gravity, and supports ittill a blow from an entering link forces the wheel up its inclinedgrooves and permits the pin to drop through the link, the wheel thenrolling back against the pin. The space between the floor-groove of thewheel and one wall of the draw-bar is occupied by a step formed on saidfloor, which acts as a back-stop to the link. The corresponding space onthe opposite side of the floorgroove is filled by a horizontal pawlpivoted to the walls in the back part of the draw-bar, and which alsoserves as a back-stop to the link; but said pawl is prolonged into afinger which projects over and rests upon one of the long segments ofthe link, and thus keeps it centered or in a horizontal position readyto enter the draw-bar of an approaching car. A dome is placed on thefront part of the drawbar, into which the coupling-pin rises, and whichprotects the contents of the draw-bar from the weather.

In the accompanying drawings,wherein like letters represent like parts,Figure l is a floor plan of the draw-bar, showing the relative positionsof gravity-wheel, backstop, and pawl. Fig. 2is an interior sideelevation with back-stop removed, showing the wheel,

grooves, pawl, pin, and dome. Fig. 3 is a de tached side View of thepawl, resting on the link to center it.

A is the floor of a draw-bar; B, the diskwheel; 0, thebottomgroovethereof; D, avertical bar to prevent the wheel from being driventoo far back; E, the back-stop; F, the pawl; G, a recess in the floor toreceive the point of the couple'pin; H, the upper groove; I, thecoupling-pin with shoulder 1; to prevent the pin being pulled throughthe dome K. A shoulder, la, is formed on the dome to serve as a bracefor the draw-bar against the edge of the car-platform.

Having thus described my invention,what I claim to be new and useful,and desire to secure by Letters Patent, is the following:

The combination, in car-coupling mechanism, of a draw-bar having a dome,K, grooves O and II, bolt D, and recess G with the wheel B, theback-stop E, the pawl F, and the coupling-pin I, all in the mannerherein described, whereby the coupling of two adjacent cars can beperformed from the platform, roof, or side of a car, as hereinbefore setforth.

In testimony whereof I affix my signature in presence of two witnesses.

WVILLIAM F. JULIAN.
